SWM-840 Install Again

I am about to install the DirecTV SWM-840 kit on my Motorhome to make my Winegard Travler Slimline SK-3005 dish compatable with the Genie HR44 Receiver. have looked through the previous threads on doing this and understand that the SWM8 is to be installed on the roof near the SK-3005. My question is how has every one who has done this installed the SWM8? Not wanting to drill holes in the roof I was thinking about only using DICOR lap sealant to attach the SWM8 to the roof by putting a layer of DICOR on the roof and pressing the SWM8 down into it and then running a bead of the sealant around the perimeter of the SWM8.
Also it appears that the SWM8 has a connection for a ground wire. I don't find anything in the SWM8 instructions for connecting a ground. Has anyone installed a ground wire and where did you connect the wire to achieve a proper ground?
Thanks for any comments that would help me with this install.

I would suggest checking with Winegard if you haven’t to ensure your HR 44 will work with your satellite dish. I have a Winegard RTT40B dish which is different than yours and had problems. The SWM840 and the HR44 would work with my dish however it would only pickup one satellite. I called Winegard and was informed I would have to remove the SWM8 and associated hardware and get a HR 24 receiver in order to get all satellites available. Highly upset as I paid the dealer to install the SWM840 and they never mentioned not receiving all satellites. Called Direct Tv and they sent me a HR24 receiver which works great and pickup all satellites. The SWM840 was installed with out a ground. It was installed using Velcro and DICRO over the mount tabs.

I have the Winegard Trav'ler Slimline SK-3005 and the SWM-8 switch and a HR-44 receiver, and it works pretty well. The switch is installed close to the Trav'ler and is attached to the roof with four screws covered with Dicor. The Dicor by itself may be enough to hold it, but if I didnt want to use screws, perhaps some 3-M 5200 Fast Cure would work.

I dont think it would be a good idea to seal the SWM-8 completely to the roof, as the switch can get hot and needs proper cooling.

I did not use a ground wire.

Here is a pic of my installation.

Stang37,
I have talked with Winegard and they are the one who indicated that the SWM-840 kit would be needed with my satallite dish and the HR44. Thanks for the info on the ground and mounting.

PJStough,
Thanks for the picture. That is about the same space I planned on installing mine. Did you raise the SWM8 above the roof or is in direct contact with the roof. Just thinking that a small space (1/8 to 1/4 inch) may help in reducing the heat buildup. I will look into the 3M product. I am thinking I will use screws and Dicor as there are a lot of other penetrations on the roof with Dicor and no leaks.
Thanks for the comments.

I just went up on my roof and looked, and it seems that the SWM-8 fits real close to the roof. Raising it up may be a very good idea since it has gotten into the mid 90s here in Iowa, my TV has been losing signal occasionally and I get an error message saying that it has lost signal from the SWM and needs to be rebooted. Rebooting power inserter does bring the signal back, but sometimes for only a few minutes, so either the power inserter or the SWM-8 switch gets over heated, and my guess it is the SWM-8. I have since switched to my ground based antenna with no problems.

So now I am contemplating raising the SWM-8 up off the roof a ways, or finding a way to make a cover for it that will not only keep it out of direct sunlight but also provide for air circulation, or I may do both.

The cover sounds like a good idea. Maybe a "U" shaped cover with 2 sides open. Could be made out of sheet aluminum pretty easily. If you do a cover please post a picture (worth a thousand words).
Thanks for the idea.

SWM-8 Installed

Got the SWM-8 installed and everything is working great. Since there has been some discussions about the SWM-8 operating hot, I decided to install the SWM on spacers to raise it above the EPDM roof I have and to allow it to get a little better air circulation around. The spacers raised the SWM about 3/8ths of an inch. You can see the pencil placed below the SWM in the pictures below. I also positioned the SWM so it is under the satellite dish when the dish is stored. Tried the installation out this past week. The ambient temperature was about 95 degrees with no clouds. I went up on the roof and placed my hand on the SWM and found it was relatively hot. I also paced my hand on the metal of the base of the satellite dish and the temperature there felt like it was approximately the same. The next morning when there was an overcast sky and the temperature was in the low 70's is did the same test. The SWM was slightly hotter than the metal on the satellite base. With those findings I think I will not install a "shade" over the SWM.
